I get this error "field.c, Line:6001, FldSetText - text longer than

The variable I store the data in is 16 bit Int (data).
is this function supposed to be reading from the field or writing to it? 
 your question suggests reading, but the code suggests writing.


the error occurs on line:       FldSetTextHandle(FieldPtr, h);
Code:
///////////////////////////////////////////////////////////////////////////////////////////////////////////
               UInt16                                      data,
controlID;
        FormType*               pForm;
        FieldType*              FieldPtr;
don't use FieldPtr as a variable name.  this is usually typedefed as 
FieldType*.

        MemHandle               h, oldHandle;
        char*                   p;
        pForm = FrmGetActiveForm();
        h = MemHandleNew(50);           // allocate chunk of memory in
this is weird.  just allocate it to the size you need.  6 is large 
enough for a UInt16.

heap
	p = MemHandleLock(h);		// prevent the chunk from moving
(lock)          
                                                                       
        //   and obtain pointer to location
	StrIToA(p, data);
	MemHandleResize(h, StrLen(p)+1);
	MemHandleUnlock(h);
	FieldPtr = FrmGetObjectPtr(pForm, FrmGetObjectIndex(pForm,
controlID));
	oldHandle = FldGetTextHandle(FieldPtr);
	FldSetTextHandle(FieldPtr, h);
	FldRecalculateField(FieldPtr, true);	// refresh the field
	if(oldHandle)
		MemHandleFree(oldHandle);
